Trannies on the corner...

[XLR8]

Well, okay. Listen, while we wait, how about sending the tranny to me and I will use in my
WOIN build? There’s no need to let it set on the shelf and collect dust. I promise to return it to you when you’re ready. No? Okay, I understand.
Anyway, that tranny’s gonna look great in whatever you decide to build around it. So, you’ve built a killer 6-gear and Stealth, what’s next on the list; belt, chain??

[GoMachV]

Belt drive for sure

So, I should build one of every color Lethal Weapon Transmission :lol

Next for me is the much anticipated. B1M Mid Motor Conversion Kit.

Haha... Yeah, I've been eyeing those on ebay and would love to scoop one up for a future build.

So I have gears, a few belts and and a couple chains but right now I'm tinkering with belts (and re-living the good ole days). So, yeah, please do a belt build next? Can the B1M accommodate a belt transmission?

[GoMachV]

I can only speak for the lethal weapon, and it won’t go mid motor. The pullies inside use a tensioner on the slack side, and that would be a problem when it’s running flipped around. The chances of skipping are a little higher but moreso there are efficiency problems running that way

The B1M ...

I'm looking to receive my kit in the next day or so.

Yeah, I reckon the tensioner position would present some problems using it in a reverse rotation mid configuration. Hey, have you ever considered using eccentrics for belt tensioning? Oh wait, Traxxas probably stole that idea from Schumacher and has patented it.

[GoMachV]

Yeah eccentrics are a great way to go, but these were designed back in the 90’s, when it was easier to wrap tape around the idler to tension it up

[NomadRacer]

Wrap tape around the idler...

I could probably get some delrin rod and machine some idlers oversized, say, in 0.020" increments? Just thinking... which is a dangerous think for me to be doing!

[GoMachV]

It was more of a quick fix for belts that had stretched but it was really easy

[XLR8]

Hmmm... What kind of tape? Is the tension idler a bearing (like the TPS one) or is a turned metal or molded plastic wheel?

[GoMachV]

Injection molded nylon supported by bearings in the case.
Just scotch tape. Nothing special. Just gotta wrap it the right direction or things can get messy

[XLR8]

Ah, I got it. So it's not adjustable and positioned in the cases to provide the correct tension - at least until the belt stretches then break out the tape. I donno, adjusting your belt tension with ordinary tape has a certain charm about it. I bet Masami would do that.

[NomadRacer]

Finally, after waiting for two weeks for the thrust bearing and washers to arrive from Canada, the 6-gear is finished.

[XLR8]

Awesome! This one looks like a trailing arm car - very cool. When will we see the rest of the build?
